How I managed to setup my Ubuntu 12.04 laptop, so I can run Crab2

CVMFS and CMSW and Grid stuff (including automatically up to date certificated and CRL's)

  • now can create a CMSSW release
cd /home/belforte/STEFANO/WORK/CRAB/CMSSW/
cmsrel CMSSW_7_0_2
cd CMSSW_7_0_2

  • but can't do scram b, so I have to copy the directory from lxplus in order to run customized cmsRun

GSI part

  • install globus-proxy-utils via synaptic
  • in my .bashrc
export X509_CERT_DIR=/cvmfs/
export X509_VOMSES=/cvmfs/
export X509_VOMS_DIR=/cvmfs/
export X509_USER_PROXY=/tmp/x509up_u`id -u`

  • and since voms-proxy-init in globus-proxy-utils is old and does not know to look in X509_VOMSES
mkdir ~/.glite
ln -s /cvmfs/  ~/.glite/vomses
  • alternatively could simply run /cvmfs/

mkdir -p /etc/pki/tls/certs/
cd /etc/pki/tls/certs/
ln -s /etc/ssl/certs/ca-certificates.crt ./ca-bundle.crt

sudo dpkg -i globus-repository-5.2-stable-precise_0.0.3_all.deb
sudo apt-get update
sudo apt-get install gsi-openssh-clients

CRAB part

  • installed locally CRAB_2_10_7_pre1 from tarball so that can edit

  • finally to setup the crab environment
source /cvmfs/ 
#source /cvmfs/ 
cd /home/belforte/STEFANO/WORK/CRAB/CMSSW/CMSSW_7_0_2

source /home/belforte/STEFANO/WORK/CRAB/CRAB_2_10_7_pre1/ 

  • now crab -create works

  • and now also crab -submit and crab -status work


  • no myproxy-* yet, need to use dont_check_proxy=1 in crab.cfg

The myproxy problem

myproxy comes with globus-proxy-utils , but it fails with

myproxy-info: error while loading shared libraries: cannot open shared object file: No such file or directory

Also is missing. I did as superuser

cd /usr/lib/x86_64-linux-gnu/
ln -s
ln -s
but then:
LapSB:TESTCRAB$ myproxy-info -d -s
myproxy-info: /cvmfs/ no version information available (required by /usr/lib/
myproxy-info: /cvmfs/ no version information available (required by /usr/lib/
Error authenticating: Connection closed.

If I try to unsetenv scram, like Crab2 does now, only get the authentication error:

LapSB:TESTCRAB$ eval `scram unsetenv -sh`
LapSB:TESTCRAB$ myproxy-info -v -d -s

For reference, the same on lxplus6 gives (making sure to use same grid-security cert. list):
